    New Builder with Bottom bracket issues

    Hi everyone, I have a Specialized Fuse Comp (https://www.specialized.com/us/en/fu...=208517-115664). I found a couple of builders that built the exact bike to electric but I can't seem to find the right piece I need in order to fit the motor in the press fit bottom bracket (PF30).

    Here are their links: 1. https://electricbike.com/forum/forum...d-l-size-frame
    2. https://electricbike.com/forum/forum...se-comp-size-m

    Both of them mention the need to use "73mm FSA PF30 BB adapter" because the "BB30 adapter does not work with this bike even it's specs say it is BB30".

    I bought this thinking it would be what I needed (https://www.fsaproshop.com/products/...44ef31e5&_ss=r) but the motor shaft won't even fit through this so I think I bought the wrong piece.

    Below are some photo's to illustrate my problem:

    This is the original PFBB30 for my bike with the bearing still inside there (can't really take it out without damaging the plastic).

    Now that same PFBB with bearing over the BBSHD motor, the shaft or 'axle' won't fit through it.

    This is the plastic piece that fits onto the original BB but is removable, it does fit over the shaft of the motor.

    So I believe the bearing is too small in diameter and doesn't allow the motor to fit, which is what Lightspeed and Tofe- both found out and got some kind of adapter. As I mentioned before, I got the adapter mentioned above but I don't think that's right because it also does not fit the motor shaft through it, it's inside diamtere (ID) is too small.

    Did I misinterpret what they meant in their mention of the adapter and in fact I need to buy something else? Can someone link what I need to buy if you know? Do I need to buy an entire new BB assembly (https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1) Is this what I needed to buy or what they were mentioning?

    Neither of them have been active for years from what I can tell (I messaged them directly and on their posts but no response). Any help is appreciated and let me know if I missed anything crucial to mention.

    Thanks

    This is what I used for a PF41. I know its not going to work for you but maybe you can have some bushings made to fit yours. https://www.empoweredcycles.com/blog...-fit-41-89-5mm

        That seems to be the exact thing I need, found a local dealer here in CA that has it in stock! Thank you for finding this
